Python中Django框架利用url来控制登录的方法

from django.conf.urls.defaults import patterns,url #or use login_required from django.contrib.admin.views.decorators import staff_member_required def login_url(regex, view, *p,**args):   """   urlpatterns = patterns('',   login_url(r'^$',direct_to_template, {'template': '1.html'}),   )   """   return url(regex,staff_member_required(view),*p,**args) def login_patterns(*p):   """   urlpatterns = login_patterns('',   (r'^$',direct_to_template,{'template':'1.html'}),   )   """   d=[]   d.append(p[0])   for i in xrange(1,len(p)):   d.append(login_url(*p[i]))   return patterns(*d)
